ANTON SOHMAOKERS, OF BIRMINGHAM, ALABAMA. V

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 323,741, dated August 4, 1885.

(No model.)

To all whom it may concern Be it known that I, ANTON ScHMAoKERs' a citizen of the United States, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented certain new and useful Improvements in Sash-Locks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a side View of my device. Fig. 2 is a face view. Fig. 3 is a vertical sectional View. Figs. 4, 5,and G are detail views.

This invention has relation to sash-locks;-

and it consists in the construction and novel arrangement of devices, as hereinafter set forth, and pointed out in the appended claims.

In the accompanying drawings, the letter A designates the side of the IVlIldOWfIEbIIlG and B B the sashes, arranged to slide in connection therewith in the usual manner. Each sash is provided on its lateral edges with the metallic wear-plates,G, which are formed with series of apertures d, at the mouths of the bored recesses e in the sash. These recesses are adapted to receive and engage the spurs of the locking devices.

D represents the lock, the main plate E of which rests upon bearings of the jamb, over a recess, F, cut therein to accommodate the working parts. The plate E is secured to the bearings by screws, and when in position is flush with the jamb-surface extending across the same under the sash guide-strips. The under side of the plate E is formed with lugs g for the ends of the pivot-rods h, to which the latches are connected and on which the spiral springs 10 are placed, said springs being each connected in a fixed manner at one end and at the other having an extension or arm, Z, engaging the latch-body and serving to keep the latch-spur out or in engaging position. The plate E is formed with apertures in and m, one above the other, near its inner margin, and at the inner side of the jamb. A third aperture, a, is made near the middle of the plate, horizontally opposite the aperture m, and a fourth opening, a, is made in the outer lower corner, horizontally opposite the aperture m. The latches P and P are of elongated form, having flattened body portions extending along the pivot-rods, and lugs 12 cast on said body portions and adapted to engage said pivot-rods. These-elongated latches extend horizontally, one above the other, and are provided each with a knobkey or thumb-piece, a, which projects outward through its appropriate aperture in the plate at m or m,as the case may be. The upper latch is provided with a stud or spur, e, which is cast on an arm of its middle portion and is adapted to project through the middle opening, a, of the plate E. The lower latch is provided with a similar spur, 2, cast on an arm at its end, as shown, and adapted to projected or engaged position, they are directed obliquely upward, so that they will securely engage the catch-recesses in the sashes. At the same time this obliquity of direction facilitates the operation of the latches in effecting disengagement prior to moving the sashes. The keys or knobs a being also directed obliquely upward, are adapted to be readily pressed inward by a downward movement...

The elongation of the fulcrumed portions or bodies I) of the latches is important in giving the necessary span or reach from the spurs to the keys and in providing sufficient bearings for the springs which hold the latches in engagement.

The knobs or thumbe'pieces may be made highly ornamental, if desired.

Instead of forming the middle spur on the upper latch and the end spur on the lower latch, the construction may be reversed, the apertures in the plate being correspondingly arranged. I
